Abstract (en)

[origin: US2018332282A1] Methods and devices for video coding using intra-coding and removing redundant intra modes from a set of candidate intra modes. The methods may determine that at least some candidate intra modes generate candidate prediction blocks that are redundant and, based on that determination, eliminate said at least some of the candidate intra modes to reduce the set to a subset. In some cases, a candidate prediction block is redundant if it is less than a threshold different from another of the candidate prediction blocks identified by one of the candidate intra modes in the set. A function may be applied to the candidate prediction block and the another candidate prediction block to identify redundancy.
